A
Gerardo Ixcoy is a 27-year-old teacher in Guatemala. He teaches in the area where having electricity is something of a luxury（奢侈品）and students have no access to mobile apps or computers, which became a problem when Guatemalan government had to choose distance education for students at home because of COVID-19.
Gerardo Ixcoy felt that he had to teach those children living far from the digital world. After all, education is a universal right and Gerardo Ixcoy thought those children shouldn't be excluded from having the education they needed. There had to be an alternative to distance education. But what was the solution?
Gerardo bought himself a secondhand tricycle（三轮车）with his savings. Once he had the tricycle, the next step was to change it into a classroom on wheels. He put a roof with a solar panel（太阳能电池板）on it, along with a screen to avoid the spread of COVID-19. He fixed a whiteboard on it so he could explain to the students the basics of primary education: math, the local language and the universal national language---Spanish.
The purpose of the solar panel is to provide constant power for a small loudspeaker so he can teach from a distance. It's a matter of respecting the healthy distance required to be safe from the virus. He, the teacher, stays outside, and the student participates from his or her house.
With that enthusiasm for education, he tries to visit his students at least twice a week, riding his classroom-cycle. The children he serves say that, although he visits them for only a few hours a week, they look forward to it. They appreciate his visit and will take advantage of it to learn.
